SARASOTA, Fla. xG Technology, Inc. has won a subcontract from Leidos to provide interference mitigation solutions and simulation models under a Defense Advanced Research Projects Agency (DARPA) shared spectrum research program.

Under the contract, xG will work on software defined cognitive radio (SDCR) platforms and lend its expertise in developing architectures that enable spectrum sharing and significantly enhance interference mitigation.

The DARPA program seeks to develop spectrum sharing technologies that mitigate the impact of spectrum congestion, a mounting problem that limits operational capabilities due to the increasing bandwidth demands for wireless communications, the use of netcentric and unmanned systems, and the need for increased flexibility in communications.
